The lovely thing about the GTP peopole is that they like to punch the cars. This might mean that a 99 with over 100k on it might hae a fairly used up transmission. I would be careful about that part of the car more then anything else as there is a lot of things you can do to the engine and the S/C but once the trany goes on these cars you are looking at around 2500 for a rebuilt one. mine is at 67,000 and its jst arocking!!!!!
